sullen - Story 143608 | Emotion Vectors in Gemma4-31B

The air in the library felt heavy with the scent of aged paper and unspoken truths. Thomas sat hunched in a leather armchair, a stack of old photographs piled on the small table in front of him. His stomach churned.

His great-grandfather, a man his family spoke of as a paragon of virtue, was pictured in the photographs with people that weren't in their family tree.

Thomas felt a knot of anger tighten in his chest. He closed his eyes, his fists clenching. He needed air. The house felt like it was closing in around him.
